Be it known that a citizen of the United States, residing at Des Moines, in the county ofPolk and State of Iowa,have invented new and useful Improvements in Anchoring Systems for Silos, of which thdpfollowing is a specification.

The present inventioncomprehendsimprovements in silos and relates more particularly to an anchoring system for silos of the knock-down frame construction.

Silos of the knock-down frame construction are often blown over or collapsed, due. to the'warping of the staves and it is an object of the present invention to provide means for anchoring the silo to its foundation to overcome these by insuring the stability of the structure.

Another object of the present invention is to provide connection between the anchoring systemand the silo which will prevent the anchoring system from pulling the staves of the silo frame apart and.thus preventing the collapse of the silo. i 3

A further object of the present invention .is to provide a system of the character aforesaid, which may be readily applied toor detached from the silo and which may be asmall package, thereby taking up a small amount ofspace when shipping 4 the same from the factory to the consumer.

of the present invention Another object is to supply a readily adjustable anchoring tively cheap in systeni'for silos which will be strong, durable and efiicient thereby rendering desirable. I

Fig. 3 is an enlarged detail of the anchoring system as applied. to the silo. Fig. 4 is a detail sectional view taken on the line H of Fig. 3 Fig. 5 is a detail elevation of one connection between the binding tie and the upper end of the silo. Fig. 6 is a detail line 6-6 of Fig. 5. Fig. 7 is a detail sectional view taken on the line 77 of Fig.9 through the upper end of the silo illustrating another connection. between the silo andthe binding ties. i

The hoops C are then placed around the silo toform a rigid structure .and thenceg 'a'top (notshown), may be placed upon the'silo.

As stated in the beginning cation, it isan object of the present invenof the specifi I tionto'provide means ffor. preventing SllOS from being blown or otherwise knocked thereof rom collapsing,- due to their warping. To accomplish these objects, I have provided an anchoring system which comprises prererably means for connecting-the upper end of the silo frame to the concrete base thereof.

Anchored within the base A are bolts being five in number, which are designed to hold the lower ends of the cables. In Figs. 1 and of the drawings, I have illustrated these bolts each consisting of a single rod having eyelets formed at the extremities thereof. The cables are connected to the upper eyelets of the bolts, as will be hereinafter described and a horizontal rod 2 exteridsthrough the eyelets formed in the lower end of the-bolts, thereby providing a suitable anchorage. In Fig. 3 of the drawing I have shown another form of an anchoring bolt which comprises one continuous rod being bent to form a pair of parallel side portions forming an eyelet to which the cables are connected andthe extremities of the rods are bent at right angles as at 30.

From this it will be seen that the concrete will fill in around the portions 29 of the bolt and over the angular portions 30 there by providing an anchorage which will be inexpensive and eliminate the extra expense {if welding the eyelets at the ends of the olt.

The eye-bolts are arranged within the concrete base as more clearly shown in Figs. 1 and 2 of the drawings. Formed within the base on each side of the silo and diametrically opposite are eye-bolts 1, at the rear of the silo,'the base is provided with an eye let 1 and a pair of eye-bolts 1 are provided within the base at the front of the silo adj acent to each side of the door-frame. The upper end of the silo is provided with three U-shaped bolts 2 each having an eyelet 3 1 formed therewith. On each side of the silo are mounted one of these U-shaped bolts 2 and the other one, is mounted at the rear of the silo frame.

Secured to the eyelets 3 at the side of the silo arecables 4: having their ends adjustably connected to V-shaped rods 5 which are connected to the eyelets 1 formed within the base A adjacent to the door-frame. The extremities of the V-shaped rods 5 are threaded and theshorter arms thereof are adjustably connected bymeans of turnbuckles 6 to hook rods 7 which are adapted to be-placed'over the .lower channel bars 12 of-the doorframe lfhe opposite or longer arms of-the V-shapednods 5 are connected to each comprising a block 8 having two parallel openings formed therein, one ofwhich nected at one end to the cable 4: by means of an eyelet 10 extends through the other said staves of the silo frame and the band 23 are opening. The threaded portions of the bolt 9 and the longer arm of the V-shaped rod 5 are provided with nuts whereby the cables may be adjusted. On the extended threaded cables at due to any shrinkage in the staves of the silo frame construction.

Extending through the door-frame and the adjacent staves'of the silo are bolts 12 which are adapted to hold the door frame in place and the outer ends of these bolts are provided with eyelets 13 to each ofwhich are connected one end of the calles 14. The lower ends of the cables 14 are I onnectedto the eye-bolts 1 by adjustable connections 15 being the same as the adjustable connections between the cables 4 and the longer arms of the V-shaped rods 5.

Connected to the eyelet 3 of the U-shaped bolt 2 at: the rear upper end of the silo are one end of each of the downwardly diverging cables 16 16 whic hare also connected at their lower extremities to the eye-bolts 1 by means-of the adjustable connections 15. A

V-shaped rod 17 is connected to the eye-bolt 1 'at the rear of the silo frame and has its extremities adjustably connected to cables 18 by the adjustable connections 15. These cables 18 diverge outwardly and are connected at their upper ends to the eyelets 3 of the U-shaped bolts formed diametrically opposite in the sides of the silo frame. The intersection points of the cables pass through eyelets 19 formed within-the sides of the frame construction as disclosed in Figs. 1 and 2.

The hoops which extend around the periphery of the silo frame also extend through the channel bars E of the door' frame which apparently hold the hoopsin their proper spacedrelation at this point,
